WILLIAM C. STEWART, 0F LYNN, MASSACHUSETTS, 'ASSIGNOIQ BY MESNE ASSIGN-MENTS, TO THOMAS G. PLANT, 0F BOSTON, MASSACHUSETTS.

To aZZQwhom 'it may concern:

1Q is a plan of the main parts shown in Fig. 8; Fig. 11 isa frontelevation of the mechanism shown in Fig. 10, omitting the clutch; Fig.-12' isa detail in section on line 12-12 of F ig. 11, looking-in thedirection of the'arrows; Fig. 13 is a side elevation showin-g the nailcarrier and the means 4for operatingthe carrier from a moving part ofthe-machine; and Fig. 14`is a section on line 14-14 of Fig. 13.

In the embodiment of the invention selected for illustration, andreferring more particularly to Figsrl to 5 inclusive, lis a nailhopper-supported on a bracket A of the.

frame'B (Fig. 8) and provided with a rotating nail elevatingwheel 2having a bearing on the lhopper and carrying buckets for elevating nailsinthe usual manner from the mass in the lower' partof the hopper, anddelivering them upon a shelf or table 3 with# 'in the hopper. The table3- guides the nails to the upper end of a roller raceway comprisingparallel `rolls 4, 4, which extend within the hopper, and are-mounted insuit- 'T he nail gear', at its rear, which is driven bya worm 6 (Fig. 2)in turn driven by friction belting 7, actuated, as may be convenient,from any running part of the machine, for instance, the sheave 7 (Figs.8 and 10). Extending throughl gear 5, is a shaft 8., on the end ofwhich, within the hopper, is mounted a bevel gear 9, the shaft 8' beingrotated by means of a friction drive 1 0, driven preferably from thesame source of powerv as the 'friction drive 7. The bevel gear 9 mesheswith a bevel gear 11 (Fig. 5) on-the upper end of 011e of the rollers 4,and each of the rollers carries'a pinion 12 which pinions mesh with eachother.'V Thus the rollers are each rotatedoutwardly in .oppositedirections (see th; fmmws in'Fig. 4). -The bearings for the rollers 4, 4are snel: (see Figs. 2 ,and 5) that. there is space leftv betweenLl.'m.sulicient for -nails delivered to the table4 3 with their pointsdown to extend between the rollers but be supported thereon by means oftheir. heads. Nails are fed to the hopper 1 sov through the chute 13,which chute extends down into the hopper at one side (Fig. 2), leavingan opening at its basethrough which nails arev fed into the base of thehopper by the weight of the nails above them 1n the chute. The openingat the base of the chute isof such size' as to always maintain the massof nails in the hopper proper at a height relatively. to the nailbuckets on the rotating wheel 2, so that the buckets may always besupplied with a sufficient quantity of nails, and yet the'congestioncaused by a great mass of nails in the hopper will be avoided. In orderto vary the amount of this yopening at the base of the chute 13, as maybe necessary, there is provided lan adjustable gate 14. This 'gate(Figs. 1 and 2) is mounted within a Slot 15, in the side of the hopper,and may be 'raised and lowered pressed stop-pin 17 .carried by thehandlein in saidslot by the handle 16 and looked in any desired-positionby placing the spring any one of the holes 18 in the side of the hopper.Thus the flow of the nailsfrom the chute to the hopper and the height ofthe nails adjacent the buckets may be regulated as may be necessary. AAsthe bucket wheel 2 *rotates it will constantly deliverto the table- 3,and to the roller raceway, a series of nails which will slide downthe-rollers by gravity to the rollers so as to be delivered from thehopper, tlieyovill, nevertheless, in many in stances remain supported bythe rollers and will slide down on top of vthe rollers until they areprevented from further movement by' the front wall of the hopper 1. Itis,

therefore, desirable that some means be provided to relieve the rollerraceway of the congestion of nails which will form 'at the frontwall ofthe hopper and to keep the lower ends of the rollers clear of improperlypositioned nails so that nails correctly delivered t0 the rollers maypass onthrough the front wall of the hopper and to tlieex- .terior-raceway 19.l To accomplish this object, in the illustrative embodimentof the invention, the rollers 4, 4 are provided adjacent to vfront wallof the hopper with a seriesI of longitudinal depressions 20, forming aribbed or corrugated surface shown most clearly in Fig. 8. Extendingover this' corrugated surface and carried by a removable cover plate 21mounted, by means of the screw clamp 21a, in the front wall of thehopper, is a leaf-spring 2 2, of such width as to effectively covervthespace' between the rollers (see Fig. 4) and of such heightabove vas willbe hereinafterA described.

the rollers that in order to pass under it the nails must dip down underit. The depressions 20l permit the heads of all correctly po sitionednails to drop below the plane ofthe upper surface of the rollers and'thus pass under the spring 22. The upper end of the spring 22'terminatesshort o the upper end ofthe corrugated surface. may be seen by referenceto Fig. 4, that'the heads of all correctly positioned nails will `slideinto the depressions 20 and will rest- It is obvious. as'

beneath thevspring 22 upon the ribs on the rollers, and that with therollers 4, 4 rotating in the direction of the arrows in said figure,thenails willbeconstantly worked upwardly against the .under side of thespring-22. The spring 22, however',vl acts. as a yielding cover plate toprevent Athe nails Vbeing fed out from between the rollers by the actionof the corrugated surfaces-. The nails,

by this device, are constantly agitated and are thus separated and aidedin their proga ress down the raceway. It is also obvious that-instead ofdropping between the rollers it extends transversely thereof, andremains supported by the rollers until it slides against the spring 22',it will either fail 'to force -itself under the spring and willtherefore drop from the raceway, .or if it doeslget that if a nail isdelivered tothe racewayso v l under the spring the ribs upon the rollersf will act as teeth to engage the nail and feed it to one side 'or theother and thus ofi o f the rollers and back into the hopper. A similaraction occurs with all-improperly 'positioned nails. It is seen thatVthe corrugated `portion of the rollers thus performs two functions,irst, to agitate the nails whereby they are separatedl so that they maybe fed singly and smoothly tothe exterior raceway; and,

second, to act as a' nail deflector to deflect from the raceway nailswhich have been iin- -v properly placed thereon.

Referring now 'to'Figs rior raceway 19, 1s of usual construction,

namely consisting of a pair of parallel bars suitably spaced apart andbetween which the 6 and 7 the extej nail extends, the nail beingvsupported on said bars by means of its head. The raceway 19 is alsovprovided withthe usual cover plate 23. The raceway 19 is preferablyremov- -able from the machine and is held in place` by means of a springcatch. 24a upon. a bracket 24 extending from the nail hopper. The upperend of the raceway has a bearing in the portion of the hopperformingabearing for the lower end of the roller raceway vand its lowerend has a vbearing upon the support for the nail-receiving cylinder 26,

rt' has been found that when operating it at.` a high rate of speedtheprogress of the nails down the 'raceway by gravity alone is not fastenough toproperlysup ly the nail receiver. To overcome this di cultv and'.efecty a lao properdelivery of the nails the vfollowing means arepreferably employed. One 'of 'the side plates of the raceway'19 is .cutaway toward its lower Vend to form an openingl at 27 (see dotted linesFig. 6) so that the nails resting 1n the slot of the raceway areexposed. Operating. inthisslot isa springe finger 28 which; forconvenience, mayl'be termed an accelerator finger The finger 2S ismounted upon one end'of an arm 29 which has an extension 3() providedwith a.

33 is a coiled spring 34 one end of .which is,

secured .to the s ide of the .race'way, ,the other end of which bearsuponthe lower end of the lever 32 in such manner that the lever ismaintained in position. so thatthe accelerator nger'QS is normally inits retracted position, or at its greatest distance-from the deliveryend of the raceway. Means hereinafter described are provided tooscillate the lever 32 uponfitsI carrying'stud, so that the acceleratorfinger 28 is given a reciprocatory motion longitudinally o'f theraceway, heilig guided in its movement by the pin and slot connection30, 31. The movement ofthe leverBQ is sii'h that the accelerator finger28 is vcarried on its backward movement (to` the right Fig. 7) beyond,say, the fourth or fifth. n'ail from4 the delivery end of the racewav,so that with its' forward '-mo'vement all of the nails .ahead of Vit arecarried forward from `the end ofl thel raceway, uickly and sharply. Thefinger 28 acts. therefore', as an acceleratorto speed the endmost nailsin the i'aceway intol position for rapid deliveryto the nail receiver.It should be particularlyY noted'that the accelerator finger 28 is, ofitself. yieldmg. invention 'it is formed of a light leaf spring.

This lis for the-reasou-that the movement-of the nails at the deliveryend ofthe raceway should be accelerated by a .very light pulshA ingaction so as to eliminate crowding and punming. against thtl naillseparating devices lt has been found iu practice-that if a stiftvfinger is used. to 'engage andlv accelerate the nails, even though mmhfinger be lightly spring pressed, the weight of. the metal alone, as thefinger ismoved forward, is sufficient to cause a jamming ofthe nails andprevent a proper separation thereof-from,

the ra-ceway. lilith. however, an accelerator finger arranged so thatthe yield is'witllm itself, and-'such yield is therefore unimpeded byany intervei'iing part. when it becomes necessary for the. finger tomove backwardly during its forward movement to prevent a jamming of thenails. such liamming is effectively overcome. .Those skilled in the artIn the illustrative embodiment of the.

plate is' spaced at- -su'fiicieiit. distance from will understand theeffectiveness of such an accelerator, as above described, withoutfurther dilation upon its action and advantages.

In the embodiment'- of'the invention selected 'foi-.illustrative pu ses,the nai'l as sorting mechanism hereto ore described hasvvbeen vshown ascombined with means ifor .delivering a group or gan of nails tothe 4naildriving. devices of aieeling machine,

Itshould v.he distinctly understood, however,

'that the type fof, heeling machine shown 'in the Raymond patent abovereferredto isinot the only'type or kind of machine; with which theinvention can be used. A Adescription 0f the preferred form of naildelivering mechanism lwill now be given. .'.Referring4 now to Figs. 6 to10 -of the within a hollow cylindrical Support 35 in turn supported.upon a bracketl C carried -by the l frame B. The support 35 is-providedwith a yoke 3T which supports the upperl end of a stud 3S upon whichthe, nail receiving cylinder 26 is rotatively mounted. The lower end ofthe stud 38 is Asupported in a bottom plate 36 (Fig. 6) secured to thesupport'. The hollow c 'vlinder is provided with an opening vin itsperiphery, .nrwhich the lower end of the exterior racewa'y '19v isadapted to' rest. To. aid in. supporting i't in position the racewaycarries a slotted bracket 19b engaging a pin i9? on' the support 35.rlhis 4lower end of the racewa'y 19 is so formed (see Fig. l7) that tlienails in the raceway'are prevented from "sliding directly out y.of itsend but are Aforced to be delivered sidewise,therefrom. In'order toobtain this sidewise deliveryof the 'nails the .illustrative embodimentof the' invention, .the 'nail receiving. cylinder 26 1s .mounted `whichextends from oneof the side rails of the race-way, across the end of theracew-ay opening and over thenail.cylinder26.- This the end of the othersiderail of the raceway so that nails may be'passed between the plate3S) and' the raceway end. T'o retain the descending'nails vin propervertical relation to the nail receiver 26 for' eflieiei'it/deliverythereto. asecorld late 39,"siinil-ar "tothe plate '39. extends .rom-theraceway below lthe plate Bflandinto a circumferential slot im. in thenail'receiver (seeFig. 6).. The nails iu resting against these platesare supl ported preferably at substantially right angles to the surfaceof the i'aceway. lu order to retain the endmost nail at the de liveryend of the raceway and against the plates 39 and39a a---pair of pins 40(Fig. T)

50 Eway past the retainin -may be provided, extending through one of.the side-rails of the raceway andV 'pressed forward by means of aIleaf-spring 41 moulited ou the raceway. The pins 40 thusynoriinallyfclose the transversely arranged exit from the raceway.

As these pins 40 are spring pressed, if any force is exerted upon theendmost nail in a sidewisev direction, the pins are readily forced backagainst the spring 4l to such an extent that the nail' may be delivered.v Many heeling machines are designed to support the shoe in themachinein such position that nails must be driven upwardly to attach theheelto' the shoe and in such cases vif nails are assprted and delivered to araceway, as is customary, with their points down, itis necessarytoreverse them before theynare driven. In other 'heeling machines thenailsare driven downwardly into-the heel, either to load the heel .or toattach the heel to the shoe. In v`the present instance,

y the parts of the machine are preferablyso .arranged that nails areselected directly from the raceway with their points down and aremaintained in this position throughi out the distributing anddriving'operations,

that is, there is no reversal of the nails after they are delivered fromthe nail raceway. To the accomplishmentv of this object, in

` the illustrated embodiment of the invention,

the nail receiving cylinder '26 has been placed immediately. adjacentto, the deliv- .ery end of the raceway 19 and with its axis 'successiverecesses in alinement with the endof' they Opening in the raceway,throughA means hereafter to be described, a series of nails are forcedby the accelerator 28-for- Wardly toward suchrecesses so that theendmost'nail rests in the recess which has been placedv at the end ofthe raceway (see Fig.

.7 Rotation of the cylinder will cause successive recesses 42 topiclroff successive nails and deliver them si'dewise out of the racepins40 when such pins are used. The lio low cylinder 35 prevents suchselected nails from falling out- Wardly from the receiving recesses 42.

` ,It has been common heretofore to. rotate a nail cylinder forreceiving a group or gang of nails by means of pawl and ratchetmechanism, but`when such driving gear is used it is necessary to providesome means to prevent overthron7 of the'rotating cylinder soithat eachvof' its nail receiving recesses may be properly alined with the openingin the raceway, and it is also necessary to provide separate devices forlocking the `rotating ratchet against backward motion.

Such meansto rotate the nail receiving cylinder have been improved byprovidingv devices whiich insure a positive rotation of the vices willnow be described. v

"A clutch of the Wellr known Horton type .is indicated (in Figs. 8 and10) at 43 V mounted on a shaft 44' which shaft is driven by a beltengaging the fast and loose pulleys 44a and 44D. The belt is shiftedfrom the fast to the loose pulley by hand, to allow of handmanipulatiomand the clutch ,is preferf .ably thrown in and out byoperation of the Fast on the shaft 44 is a sleeve.

machine. 45 (FigsI 10 and 11,) proif'idedwith one or more spring pressedpins 46 which engage a second sleeve 47 on the shaft 44. The secondsleeve 47 is provided with a pair of longitudinal slots 48. A thirdsleeve 49 on the shaft 44 is pro-vided with a pair of longitudinal lugs50 at the end adjacent the sleeve 47, which' extend into the slots 48 onsaid' sleeve, said slots'acting as guideways for the lugs inlongitudinal movement of the sleeve 49 upon theshaft. The sleeve 49 isprovided with a cam groove 51 'and -with a4 worm 52. The bracket C inwhich the shaft 44 is journaled is providedwith an auxiliary bearingwhich supports a roller-stud 54 (Fig. 6) with which the worm 52 isadapted to mesh. With suoli a construction, it is evident that as theworm 52 is rotated in one direction (as illustrated, toward theoperative, viewing Fig. 11) the longitudinal y movement to the right,controlled by the cam 5l. is such that the threads of the worm turnidlybetween the teeth of the 'gear 55 and do not rotate said gear.- Onthe other hand the longitudinal movement of the worm to the left, whilestill rotating in the same directioin will operate to turn the gear 55(in the direction of the arrow, Fig. 7 with greater speed than wouldbe-possible if no longitudinal movement were given'to the sleeve 49.Thus the nail-receiving cylinder 26 is positively driven with astep-bystep motion by means constantly in working engagement'the feedingmovement being accelerated by the construction of the driving devices sothat the suddenv start and stop of the receiverv incidental toreceiving, nails singly from the raceway at high speed` is controlledand the receiver locked by its f actuating means. Over-running of thevnail receivin grooves in the receiver, so that'a .nail .cou d not beproperly .delivered to its receiving reces'sfer shipping of nails isprevented. The, connection between the sleeves and 47, by means o1the-spring pressed pms 46, acts as a safety device to dlsconnect theworm 52 from the shaft 44 should the nail cylinder 26 or other movingparts be-V One 4wall of 'the cam groove 51 in the -sleeve 49extendsjslightly above thesurface o f the sleeve and .this extendingwall is pro vided with a cam surface 56 Fig. 11).

' Adapted to engage this cam su face (see er 57 on the lower arm 'of aFig. 10) lis a. rol bell crank lever 58, pivotally mounted upon a stud59, which is rotatively mounted upon a stud 60, extendin from thebracket C. The upper arm61 o the bell crank lever 58 is adaptedto engagewith the lever 32 which i carries' the acceleratorfinger 28 (Figs. A64and 7). The'roller 57 is normally pressed toward thecam 56 by means of asprmg 62'extending between a lug on the .bell crank lever 58 and a lugon an' extension 59'l formed onthe supporting stud 59. The stud59' isnormally maintained in4 position for the roller 57 to engage the cam- 56by means 'of a spring pressed pin 63 mounted in a socket on the bracketC and adapted to engage a recess '64 in the extension 59?. The stud 59carryin the bell crank lever 58 is rotatively mounte on the stud 60sothat the upper arm .61 of the bell crank may be: withdrawnfromengagement' withthe lever 32 of the accelerator to permit ready removalof the raceway 19 from the machine. 'With such a construction it is seenthat with each rotation of thel 'sleeve .49 and therefore with eachstep-bystep movement of the. nail receiving cylinder 26 theaccelerator-linger28fis reciprocated to engage behind a number ofendmost nails in the raceway 19 and then to force them quickly forwardto be engaged, one by one,

by the nail-receiving recesses 42 and re' moved from the raceway. Thereason for provldm an accelerator to speed the lowerlnost nal `s 1n theraceway forward toward the nail-receiving cylinder,l is, that if thevnails were allowed to slide down the race- Way by gravity alone theywould not be supplied fast enough to fill every recess in the cylinderas it rotates past the delivery end of the rat-exray. Means is thusprovided to fill cach successive recess -l2 of the cylinlprovided with aseries of openings 66 (shown in dotted lines in Fig. 7) which normallyare out of register .with the nail-receiving recess 42 and are somaintained by means of a spring 67 secured .at one end to the coverplate' 65 and at its other end to the cylinder 26, and extending withinla recess in the cylinder. The cover plate is maintained in positionwith its holes 66 between the nail-receiving recesses 42 by means of apin 65iL extending from the cylinder 26 and into a slot 65" in the coverplate. The engagement of the ends of the slot with. the pin limitsthemovement of the cover plate in either direction around the stud 38.cover plate 65 is alsoprovided around its A periphery with a serie', oflugs or-'teeth 65 (see dotted lines Fig.- 7), one for each of the,series of holes 68 (Fig. 6)' which coincide fromwith the nail-receivingrecess 42 and each of these holes 68 depends a coiled wire distributingtube. 69 as is usual in heeling machines. uting tubes project into adistributer platek 70 (Fig. 8) which is in the form of a removable blockhaving therein a series of holes corresponding in number to the numberof nails it is deslred to drive in a heel.v These holes are arranged',in the form of a 'horseshoe, as is customary7 so that the nails may bedriven evenly within the outer periphery of the heel. Below thedistributer plate 70 is mounted a nail carrier-..71 upon an arm 72adapted to swin'gabout a stud 73 on the main frame and move the nailcarrier from a position beneath' the distributer plate to a positionbeneath' the nail driving devices. One form of means for thus moving thenail carrier from a moving part of the machine is shown in Figs. and 14,wherein B is or may be part' of the 'machine supporting fran'ie'carryingthe stud 73 011 whichis the hub 150 of the carrier arm72.- The hub 150has a gear segment 151, the teeth of which mesh with. the teeth 'ofa onthe upright shaft 153, the lower end of which carries a gear 154 whichis engaged by a segment 155 formed on one end of a lever-.156 pivoted at157 to the main frame. Said lever 156 carries at its other' end a pin orroll which is held in engagement with an actuating cam 159 by means of aspring 160, one end of-Which is connected to the end of the lever 156 at161 and the other end toa.

Thecam 159 is secured tothec'ounter shaft 162 mounted in the main frame. and driven The lowerend of. these distribA The recesses 42 for a'purpose to be hereinaftergear 152. mounted from the raceway may be delivered from the cylinder asa group or gang through the distributing block 70 and into the nailcarrier 7l, means is provided for actuating the cover plate 65 to bringits holes 66 beneath the lower ends of the nail recesses 42 just at"lthe time when the'nail carrier has reached its position beneath thedistributer block. The preferred form of suchineans comprises a springpressed pin 74 (Fig. 8) mounted onthe nail-carrier arm 7 2, which pin isadapteid to engage, on the movement1 of said arm to bring the nailcarrier under the nail disl tributeigi he. dependingv arm 75 of' a smallbell ciant lever mounted on a stud 76 extendini; from the bracket whichsuppoits the nail distliibuter 70. To the other arm 77 of this si all'vbell crank lever-there is pivoted a rod 7 tithe other end of which inturn is ltoj, one end of a lever 79 pivotally Vupon a stud SO on thebracket C. end of the lever 79 is so formed as to be ladapted to engagethe outer end vSl of a lever lplivotally mounted on the bottom plate 7).The other end 82 of this lever i, tadapted to project between and engagethe teeth 65C on the periphery7 of the cover plate 65. The end S2 ofthis lever is normally i with the teeth 65c by meansv of a coiled spring83 arranged to normally force said end outwardly, stop pinv St limitsthe outward in vement of said end of the lever. A spring gliamaintainsthe bell crank lever arm- 7 5 n finally in positon tobe engagedby the pijn 74. The rod 78 may be pro-vided `with a thri buckle 781 sothat adjustment may be ma i e f or wearer for other purposes as may`|desired. lith such a construction whenl'the carrier arm 72 is swung/to lorinpthe carrier 7l beneath the distributer 7d the spring pressedpin 74 engages the arin 75y of the bell crank lever and draws the rod 78downwardly thus actuating the lever 79 to engage the outer end of thelever 8].-82 and force its inner end into engage- 4ment with oneof theteeth 65C so as Yto roy tate the' cover plate 65 about the stud 38 andbring its holesl 66 beneath the nail-receiving recesses 42.

`The rotation of the shaft 44; is initially startedpreferably by meansof the follovv ing mechanism: After the nail 'carrier 7 1 has received agang of nails from ,the nail cylinder by actuation of the 'cover' plate65,l

as above described, it is moved, as is cus- ,toinary in heelingmachines',..from its position beneath the distributer to alpositionbeneath the nailing devices. On the beginning of the-movement 'of thecarrier 71 from l naintained out of engagement' the distributer' aspringpressed pin 85 (Fig.

8) mounted' in the carrier arm 72 engages` the lower end 86 of a smallbell crank lever pivoted at 87 on the bracket which support." thedistributer. lTo the other arm 88 of this small bell crank is pivotedthe lower end of a rod 89 the upper end of which is in turn pivoted to acrank 90 on a rock shaft 9i mounted in bearings upon the bracket (Fig.l0). The rock shaft 91 also carries a crank arm 92 adapted to engage Yina recess at one end of a trip-lever 93 pivoted at 94e on one of thebearings of the shaft 44. The

rock shaft 91 also carries a stop arm 95 ing said crank arm and theotherendI held from movement in a lug 97* the bracket The rod89 may alsoI beprovided with a turn buckle 89a if desiied. Vith such a' construction itis readily rseen that as the carrier arm '72 moves the nail carrier Ilaway from the distributer 70 the pin 85 willl movetlie bell crank Sti-88in such a direction as to pull downwardly on the rod 89 andthereby movethe crank arm 92, and the stop arm 95, away from'the lever respective'y.The removal ofthe stop arm 95'from iis-lug allows the clutch to engageand starts rotation of the shaftf-l. rllhe removal of the crank arm 92outof the'recess in leverf93 is for the purpose of performing etendingfrom 93, and thesstop 96 on the Horton clutch,

another function as will hereinafter appear.

as to' have about its periphery a sufficient U nun/iber of nail recesses42 to accommodate the" greatest number ofl nails that may be ut/llizedin nailing a heel ofany size upon a shoe. In the present instance thecylinder 26 has been shown with fourteenv such nail recesses. It isobvious, however, that in different sizes of" shoes a different numberof nailswill .be required as there is more or less space in each-toinsert the nails. `:Thus in small sizes or in the heels of ladies shoesitV is desirable to use' only five nails, Whereas on the larger sizes,and particularly in' the larger sizes of mens shoes, it is desirable touse as many as ythirteen nails. It is therefore seen that it is highlydesirable that the izo machine be provided with means forpieydetermining lthe number, of nails which shall l from said cylinder tothedriving mechan ism of the machine as may lbe necessary for theparticular size of heel being operated on).

To the accomplishment of this objectthere'" 85 on the rock shaft 91,having one end' enga'othas been provided on the machine what may hetermed a counting mechanism, which is under control of the operative asto its setting. and may be set to deliver any desired number of nails upto the full capacity of the mul-receiving cylinder. Although there arefourteen nail recesses in the illustrative nail-receiving cylinder it isobvious that one of them will always b e atv theI end of the racewaywhen the cover plate is moved to deliver the nails as a gang, and,therefore, as thenail in the raceway is held therein by its head itcannot'be delivered to the cylinder. .lf such delivery could 'take placeit would also allow the ne-xt nail in the raceway to immediately fallintosaid recessand slip into the distributer on top of thefirst nail,and so on, with the resultl that the delivery of nails` would becomechoked. T here is, therefore, av blank in the bottom plate 36 at theraceway end-.and thus the capacity of theA nail receiving cylinder shownfor illustrative purposes is thirteen nails.

The lever'93 above referred to is used in connection with the mechanismfor counting varying predetermined numbers of nails into -the n-ailcylinder 26. The preferred construction of this mechanism and itsconnection with the lever 93 will now be described. e

Mounted on a hollow stud 97 (Fig. 12) extending transversely through thebrackets C and at right angles to the axis of the shaft 44 is apinion98, which may be termed .a counting wheel. This pinion is provided witha series of circumferentially arranged holes 99 (Fig. 9). lithin thehollow stud 97 extends a pin 100 having on its end adjacent tov pinion98 an arm 101 which extends from the pin 100 radially of the pinion 9.8'and is provided on its surface, next the surface of the pinion, with aprojection or pin 102 adapted to enter any one of the series of holes 99and thus lock the -arm and pinion together. The-other end of the pin 100is provided with a disk 103 (Figs. 10 to 12) having marked'thereon aseries of figures, which disk may be turned by'means of a thumb-nnt 104to bring any on-e of the figures in the series opposite an index 105 inthe bracket' Cm The arm 101 is normallyT maintained with its pin 102 inengagement with onel of the `holes 99 by means of an expansion spring10G having bearings between the disk 103 and lthe bracket C but said pin102 may be easily disengaged from the hole in which it happens to be bypressing inwardly on the disk 103` thereby compressing the spring 106and sliding the pin^100through the hollow` stud 97. Encircling thehollow stud 97 is a coiled spring 107, having one end secured to the`stud and its otherend secured to the bracket C so that when the pinion.98 1s turned in one direct-ion .it tends to constantly wind up thespring 107.

.'f nthe sleeve 49 which carries`the worn-l 52 is a circumferential rib108 provided with a broken away portion so that lil does""11ot lextendwholly around the sleeve. The pinion 98 is so located beneath the` shaft14 that when the sleeve 49'rotates. t-he rib 108 engages between theteeth of the pinion and in themovement 'of the sleeve to the left (inFig. 1'1),operates to .turn the pinion in a contra-clockwise direction.The cut out portion of the rib 108 is so placed that on the -inovementof the sleeve 49 to the righty (in Fig. 11) the teethof pinion 98 arenot engaged, and no movement is therefore' given to 'the pinion, butduring this movementl of the sleeve 49 to the right the rib 108 is movedto a position 'Where it can, and does, engage the next tooth of thepinion at the beginning of the next movement of the sleeve 49 to theleft. Thus as 'long as the sleeve i9 continues its reciprocations thepinion 9S will be given'repeated impulses and will be turned step bylstep. Thev pinion 98 is prevented from turning backward, through the'force exerted by the spring 107, during the ytime that. the cntawayportion of the rib 108 is moving past it. by means of a pawl 109pivotally mounted upon' the bracket C (Figs. 9 and 11) which ismaintained in engagement with the teeth of the pinion by a loop-spring110 having one end 'engaging the pawl and its other end mounted in thebracket 'C. It is obvious that if, after the pinion 98 has been rotatedas described, the pawl 109 is moved from engagenient with the pinion 98the then tensioned spring 10T will operate to immediately tu-rn thepinion backward the entire distance which it ha`A been moved forward. Toengage and disengage pawl 109' from the pinion 98 is one of thefunctions of Athe lever 93 heretofore referred to. To the end'of lever93 opposite that engaged b v the crank arm 98 is pivoted a rod 111 whichat its other end is provided with a pin 112 adaptedA to engage a pin'1123 extending from the pawl 109. The pins 112 and 113 are normallymaintained ont of engagement, so that the spring 110 may actto keep thepawl 109 in engagement with the teeth of the pinion 98, b v means of acoiled ion spring 114 surrounding the-rod 111 having one end secured tothe rod itself and its other end secured .to a loose collar on the rod,which collar is prevented froml movement in a direction toward the lever03 by means of a stop lug 116 extending from the bracket C (Fig. 11).The end of the rod 111 extends across the face of the pinion 98 in' suchosition that as the pinion rotates the en of the rod will be engaged bythe end of the arm 101. Such engagement will force the rod 111 to theleft (Fig. 11)

therebyy causing the pin 112 'to engage the p1n'113 and carry the pawl109 out of engagement with 'the teeth of pinion 98. lVhen this occursthe tensioned spring 107 operates to rotate pinion 98 backward to itsstarting or zero position. This zero position is determined bytheengagement of a lug 117 12) on the face of the pinion with the.

under side of t-he rod 111.

It should be noted that when the crank 'arm 92 on: the rock shaft 91 isin engagement with the recess in the level' 93 the rod 111 has beenmoved to the left (Fig. 11)

and the' pawl 109 is then out of engagement Thus thecrank arm 92, andwith it the rock shaft 91, is maintained in such position that the stoparm 95 of the clutch is not in position to be engaged by the lug 90 tothrow out the lclutch. As soon, however, as the' rod'111 is moved to theleft (F ig. 11) by the engagement therewith of the rei ving arm `101,the lever 93 is moved in a direction to bring its end 93a out ofengagement with the crank arm- 92 and the spring `96 on the rock shaft91v then operates to move the crank arm 92 inwardly into engagement witthe 'recess in the lever 93 carrying with it the stop arm 95l intoposition to be engaged by the lug 90 to throw out the clutch and stoprotation ofthe shaft 44. lilith such a construction it is readily seenthat if the movable arm 101 on the pin 100 be placed in the hole inthepinion 98 farthest to the right (Fig. 9) thirteen impulses will be givento the pinion 98 by the engagement therewith of the rib 108 before theend of said arm 101 comes into engagement with the end of the rod 111 tomove the rod, and with it the lever 93, to a posit-ion where the stoparm 95 of the clutch is placed in a position to be engaged by the lug 96and thus lthrowout the clutch and stop'rotation of the shaft 44. If,however, the pin 102 on the arm 101 is placed in the hole farthest tothe left (Fig. in the pinion 98, only tive impulses will be given tosaid pinion before the stop'arm 95 is placed in position to be engagedby the lug 96 and thus throw out the clutch and stop rotation of theshaft 44. If the arm .101 is placed in engagement with any one of theremaining holes in the pinion 98 other numbers of impulses will be givento the pinion between the limits 'of five and-thirteen, according to`the angular distance' of the hole from the end of the rod 111. The

series of numbers on the face' of disk 103 correspond to the number ofimpulses given to the pinion 9S when the crank arm 101 is located in anyparticular hole 99. Thus, in Fig. 11, the numeral 9 on the disk 103 isshown as being placed opposite the index 105 and, therefore, the arm 101has been placed in such position that nine impulses .will be given tothe pinion 9S before rotation of the shaft 44 is stopped. lAs the pinion98 is given an'im'pulse, or is turned the distance of one tooth, foreach complete rotation of the sleeve 49 on the shaft la and as eachcomplete rotation of the sleeve 49 ywill turn the nail receivingcylinder 2G about its stud 38 a distance equal to the space between twoof its nail receiving recesses 12, it 'is seen' that for each impulse ofthe pinion 98 a nail is delivered to one of the recesses of thenail-receiving cylinder 26. As the number of impulses to be given to thepinion 98 is entirely within the cont-rolof the operative, the number ofnails delivered to the nail-receiving cylinder 26 may be predeterminedby the operative.. If then, the nailing devices of the machine are tooperate upon small sized heels the operative simply turns the disk 103to a position with the numeral 5 say, beneath the index 105 and thenail-receiving cylinder 26 will, when y the clutch is thrown in, beturned only far e-- gh to pick off from the end of the racen way tivenails. If, on the other hand, the operative is nailing large sized heelswhich require, say, thirteen nails it is simply necessary for him toplace the numeral 13 on the disk 103 beneath the index 105 and thenail-receiving cylinder 20 will be operated to pick off exactly thirteennails from the The machine is thus provided with means forypredetermining the number of nails to be delivered as a group or gangfrom the nail-receivingcylinder and, in thisv instance, to the nailcarrier of a heeling machine. f

In operating the nail. delivery mechan ism, when, say, five nails Vareto be delivered as a gang from the nail cylinder, a distribu ter blockis inserted in its supportingbracket whichhas but five holes'and onlythe iirst tive of the thirteen distributing tubes 69 arey used, countingto the left (Fig. 7) "from the hole in the bottom plate 36 beneath therecess in the-nail cylinder marked 1.. Each time, then. that the clutchon the shaftllll is thrown into and vout of operation, nails will bedelivered to six of the recesses 4-2 which includes the recessremaining-at the delivery v end of the raceway 19.' ,Onmovement of thecover plate 65, however, only the .five nails beyond the raceway aredelivered from'the nail cylinder as heretofore explained. -When 'thelcounting mechanism is again operated,

the raceway becomes the first of the new series of nails starts from adifferent one of therecesses'42.

received by the cylinder a new point on the circumference of the coverplate is in position for engagement by the trip 'lever 81- 82. It '1sfor this reason that a tooth is ,provided for each recess 42. lith sucha construction nails can be delivered to the distributer at the end ofeach forward movelment of the nail `receiving cylinder and it is 'thebase of the chute having been adjusted. so that the nails are maintainedat the proper height within the hopper for the best delivery of the sameto the raceway, the

clutch of the main machine is thrown in and stopped as hereinbeforedescribed.

thefrollers 4, 4 of the roller raceway within the hopper are constantlyrotated and nails are constantly delivered to the table 3 fordeliveryfrom the hopper to the exterior raceway 19. If a medium sizedheel is being operated upon by the nailing devices the disk 103 is set,for instance, with the numeral 9 opposite the index 105 (as shown inFig. 11). It will be assumed that there are no nails in thenail-receiving cylinder 2G and that the nail carrier is in its positionbeneath the nailing devices. Then as the machine begins lo operate thenail carrier '71. is moved about its stud T3 and brought beneath thenail distributer 70. In this movement the cover plate (S5 is moved, butas there are no nails in the cylinder none are delivered from thecylinder to the distributer and lfrom thence to the nail carrier. On themovement of the nail carrier away from the nail distributer, however.the bell crank lever SG-SS moved in such manner as t :tl1row the crankarm 92 and the stop arm 95 on the yrock shaft 01 outwardly,v'liichthrows in the clutch and iinniediately starts rotation of shaft- 44.This shaft in turn coimmlnicates'rotarv movement to the nail cylinder 26and said cylinder is rotated suiiiciently to pick off from the nailraceway nine nails, at the end of which time the clutch is again thrownout and rotation of the shaft- 44 is On the next movement of the nailcarrier to bring it beneath the nail distributer the bell crank lever75-77 is moved in such direction that the lever 81-82 is moved about itspivot to engage one of the teeth on the cover plate It is thus seen thateach new l 65 and move the cover plate so that the nine nails in thereceiving cylinder are delivered therefrom as a gang. These nails dropthrough the distributing tubes 69 and through the distributer 70 intothe holes arranged for their reception in thenail carrier T1. The nailcarrier, immediately upon'` receiving its gang of nails, is movedforward to place these nails under the vdriving devices and as it movesforward the bell crank 813-- 88 is again rocked to move the parts tothrow in the clutch and again rotate shaft 44 and the nail cylinder2t5to pick off nine more nails and hold them in the nail cylinder inreadiness for delivery to'the nail carrier on its next movement to aposition beneaththe nail distributer. This cycle of operations is ofcourse kept up indefinitely until the main clutch of the machine withwhich the assorting and delivering mechanism is combined is thrown outand work thus stopped.

This invention can obviously be changed in many of its details ofconstruction without altering its scope and, therefore, it is to bedistinctly understood .that the invention as definedl in the followingclaims .is not limited to the particular embodiment of the mechanismherein shown. in the d awings and used for illustrative purposes.
